A letter from the desk

You finished the documentary. You still don't know why it died.

You know the feeling. Forty minutes of footage, a dramatic soundtrack, a founder in a courtroom sketch, and the credits roll before anyone explains what actually broke. The comments under these videos say it better than I can:

"The mark-to-market explanation was the clearest part for me."A viewer, on the one part of an Enron video that explained the numbers
"How many other Enrons are there now?"A viewer, asking the question nobody answers

Here's what I've learned from reading what dead companies leave behind. They rarely die from one scandal. The numbers turn first, usually the profit on each sale or the debt, and everyone ignores them until the story breaks.

So I put twenty collapses in one book, laid out the same way every time: the dates, the four numbers that matter, the day it became impossible to ignore, the one mechanic you need, and the number in the filings that turned first. Then one check you can run today on any company.

A free lesson from the book

How a bank full of government bonds went broke in a day

Silicon Valley Bank held US Treasury and agency bonds, about the safest things money can buy. It failed on March 10, 2023. Here's the same bank seen two ways.

Before: the headline

Deposits tripled, from about $62 billion at the end of 2019 to about $189 billion at the end of 2021. Loans mostly fine. A big pile of government bonds, labeled "held to maturity". It looks rich and careful.

After: the drawer

The footnote in the 2022 annual report:

Shareholders' equity, the cushion$16.0B
Unrealized loss on held-to-maturity bonds$15.1B

Valued at market prices, the cushion was nearly gone months before the run.

Why the headline missed it: when rates rise, old low-rate bonds fall in price. Labeling them "held to maturity" lets a bank keep them at cost and push the loss into a footnote, on the promise it'll never have to sell. The promise only holds while depositors stay. More than 90% of SVB's deposits sat above the $250,000 insured limit, and on March 9 customers asked for $42 billion back.

Run it yourself on any bank

  1. Open its latest 10-K on the SEC's free EDGAR site.
  2. Find the note on held-to-maturity securities and write down the unrealized loss.
  3. Find total shareholders' equity on the balance sheet.
  4. Divide the first by the second. Over half is a warning. Near all of it is an alarm.

That's one of the nineteen checks in the book, each learned from a real collapse.

Who made this

Walt Brennan

Walt Brennan, Fault Line Ledger

I host Fault Line Ledger, where I read company filings out loud and explain where it really went wrong. I believe the cause is in the filings before it's in the news, and that anyone who can read a bank statement can read a balance sheet if someone explains it plainly.

Questions

Before you buy

I've watched the documentaries. Is this the same stories again?

No. The documentaries tell the drama. Each file here is the cause: the dated timeline, four key numbers, the turning point, the mechanic behind it and the sources, so you can check every claim yourself.

Do I need to know finance?

No. Every term is explained the first time with an everyday example, like a phone bill or renting back your own house, and all 18 are collected in one glossary at the back.

Will it tell me which stocks are next?

No, and that's on purpose. It gives you nineteen checks that turned up before real collapses, so you can run them yourself on any company you own or work for.

How do I get it, and does it work on a phone?

You download a 58-page PDF right after paying. It's laid out at a book page size that reads well on phones, tablets and laptops, and prints cleanly.

Can I get a refund?

All sales are final. This is a digital download you get right away, so we don't offer refunds. This doesn't affect any rights you have by law. The free lesson, the contents and six real pages are on this page so you can check before buying.
